Description

Technical Field

[0001] This application relates to the field of container welding, and in particular to a transverse welding apparatus for the top of a container. Background Technology

[0002] A shipping container, also known as a cargo container or cargo box, is a set of tools capable of loading and unloading goods using mechanical equipment. A shipping container includes a supporting frame, a floor plate installed on the bottom side of the supporting frame, a rear door panel installed on one side of the supporting frame, three side panels welded and fixed to the sides of the supporting frame, and a top plate installed on the top side. When welding the container top plate, the left and right sides of the top plate are typically welded and fixed to the supporting frame, and then the front and rear edges of the container top plate are welded to the supporting frame. The welding and fixing of the front and rear edges of the container top plate is generally referred to as the transverse welding of the container top.

[0003] The transverse welding device for container roofs includes a gantry frame, a horizontally arranged transverse linear module mounted on top of the gantry frame, a lifting linear module mounted on a sliding platform of the transverse linear module, and a welding torch assembly mounted on the sliding platform of the lifting linear module. A conveyor platform is typically installed under the transverse welding device. The container with the roof to be welded is placed on the conveyor platform, and after being conveyed, the area to be welded is aligned with the welding torch assembly. Driven by the transverse and longitudinal linear modules, the welding torch assembly completes the welding between the container roof and the front and rear edges of the supporting frame.

[0004] Regarding the aforementioned technologies, when the top plate is placed on top of the container, the middle of the front and rear edges of the top plate is prone to arching upwards, which means that the welding quality of the transverse welding device on the container top needs to be improved. Utility Model Content

[0005] In order to improve the welding quality of container roofs and make the welding quality more stable, this application provides a transverse welding device for container roofs.

[0006] The container roof transverse welding device provided in this application adopts the following technical solution: A transverse welding device for a container roof includes a mounting frame and a welding mechanism; the mounting frame includes two side platform frames arranged opposite each other and a support frame installed between the two side platform frames; the support frame has a transversely arranged welding beam; the welding mechanism includes a welding head, a lifting assembly for driving the welding head to rise and fall, a translation assembly for driving the lifting assembly to move laterally and installed on the welding beam, a pressure plate member disposed on the side of the welding head away from the support frame and arranged laterally, and a drive assembly installed on the side platform frame and driving the pressure plate member to rise and fall.

[0007] By adopting the above technical solution, the installation frame is equipped with a side platform frame and a support frame to provide support for the device. A welding mechanism is arranged on the installation frame. This mechanism can move the welding head through translation and lifting components, facilitating welding at different positions and improving welding efficiency and quality. A transverse pressure plate and a drive assembly for raising and lowering the pressure plate are arranged on the side of the welding head away from the support frame. This flattens the arched container roof, resulting in more stable welding quality.

[0008] Optionally, the bottom of the pressure plate is provided with a buffer pad structure.

[0009] By adopting the above technical solution, a buffer pad structure is set at the bottom of the pressure plate component, which can provide a buffer support when the pressure plate component presses on the container top plate, thereby reducing the damage of the pressure plate component to the container top plate.

[0010] Optionally, the mounting frame is further provided with a limiting component to prevent the pressure plate from falling; the limiting component includes limiting cylinders respectively arranged corresponding to the ends of the pressure plate; the limiting cylinders are arranged horizontally and the limiting piston rod of the limiting cylinders is arranged on the lower side of the corresponding ends of the pressure plate.

[0011] By adopting the above technical solution, a limit component is installed on the mounting frame. The limit component can provide a safe limit to the pressure plate component through the piston rod of the limit cylinder. When the pressure plate component falls, the extended piston rod can support the pressure plate component, reducing the probability that the pressure plate component will fall directly onto the top of the container and improving the safety of the device.

[0012] Optionally, the lifting assembly includes a lifting bracket, a lifting platform vertically slidably mounted on the lifting bracket for mounting the welding head, a lifting screw rotatably mounted on the lifting bracket and arranged vertically, a first screw nut mounted on the lifting platform and cooperating with the lifting screw, and a first drive motor for driving the lifting screw to rotate.

[0013] By adopting the above technical solution, a lifting assembly for connecting the welding head is set up. The lifting screw, the first screw nut, and the first drive motor in the lifting assembly drive the lifting platform on which the welding head is installed to rise and fall, thereby controlling the lifting position of the welding head and improving the welding accuracy and stability.

[0014] Optionally, the translation assembly includes a transverse slide table that is laterally slidably mounted on the welded crossbeam, a drive rack that is laterally mounted on the welded crossbeam, a drive gear that is rotatably mounted on the transverse slide table and meshes with the drive rack, and a second drive motor that is mounted on the transverse slide table and is drively connected to the drive gear; the lifting bracket is mounted on the transverse slide table.

[0015] By adopting the above technical solution, a translation component for installing the lifting support is set up, enabling the lifting support to move horizontally on the welding beam. The drive gear on the transverse slide meshes with the drive rack on the welding beam, and under the drive of the second drive motor, it drives the lifting component and the welding head to move laterally, realizing the movement of the welding head in the transverse direction, which facilitates the transverse welding operation on the transverse gap of the container top.

[0016] Optionally, the translation assembly includes at least two transverse slides, each of which is equipped with the drive gear and the second drive motor.

[0017] By adopting the above technical solution, at least two transverse slides are set up, along with drive gears and a second drive motor on the transverse slides. Lifting components and welding heads are installed on the corresponding transverse slides, enabling at least two welding heads to weld simultaneously from different positions in the gap, thereby improving welding efficiency and welding quality.

[0018] Optionally, the lifting bracket is provided with baffle assemblies on both sides of the welding head.

[0019] By adopting the above technical solution, baffle assemblies can be set on both sides of the welding head to block the spatter generated during the welding process, thereby reducing the impact of the spatter on other welding positions and the surrounding environment.

[0020] Optionally, the support frame has a horizontally arranged support platform.

[0021] By adopting the above technical solution, the support frame has a horizontally arranged support platform, which can provide horizontal support for the operator to stand and walk, facilitate the operator to observe the welding position, facilitate the operation of the welding mechanism, enable the welding process to proceed smoothly, and ensure the stability of welding quality.

[0022] Optionally, the support frame is lifted and installed between the two side platform frames, and each side platform support is equipped with a lifting hydraulic cylinder to support the support frame.

[0023] By adopting the above technical solution, the lifting hydraulic cylinder set in the side platform support is conducive to the lifting control of the side platform support and the support frame, flexibly adjusting the height of the support frame, and facilitating the maintenance and repair of the welding mechanism.

[0024] Optionally, two sets of the welding mechanisms are included, with the two sets of welding mechanisms arranged at intervals along the transport direction of the container.

[0025] By adopting the above technical solution and setting up two sets of welding mechanisms arranged at intervals along the transport direction of the container, it is possible to weld both the front and rear seams of the container's top plate, thereby improving welding quality and efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A transverse welding device for container roof, which provides stable support by setting up an installation frame, includes a welding mechanism with lifting components, translation components and welding heads, improves the accuracy of welding head control, facilitates welding of gaps at different positions on the container roof, and improves welding efficiency and quality; 2. By setting up pressure plate components to flatten the arched container top, welding becomes smoother and the welding quality becomes more stable. The bottom of the pressure plate components is also equipped with a buffer pad structure to reduce damage to the container top. The mounting frame is also equipped with limit components to reduce the probability of the pressure plate components falling directly onto the container top, thus improving safety. 3. By setting at least two transverse slides, drive gears and a second drive motor, as well as lifting components and welding heads on the transverse slides, at least two welding heads can be welded simultaneously, improving welding efficiency; setting two sets of welding mechanisms can simultaneously weld two container top plate gaps, improving welding quality and efficiency.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a transverse welding device for the top of a container. (Refer to...) Figure 1 A transverse welding device for the top of a container includes a mounting frame 1 and two sets of welding mechanisms 2 arranged on the mounting frame 1. The two sets of welding mechanisms 2 are arranged at intervals along the conveying direction of the container 3.

[0035] Reference Figure 1 and Figure 2 The mounting frame 1 includes two side platform frames 11 arranged opposite each other on both sides of the transport path of the container 3, a support frame 12 mounted between the two side platform frames 11 and located on the upper side of the container 3, and lifting hydraulic cylinders 111 mounted on the side platform frames 11 for driving the support frame 12 to rise and fall. The support frame 12 includes a support platform 122 and two support gantry 121 respectively mounted on both sides of the support platform 122 and corresponding to two sets of welding mechanisms 2. Each support gantry 121 has a horizontally arranged welded crossbeam 1211 perpendicular to the transport path of the container 3. The welding mechanisms 2 are installed at the corresponding welded crossbeams 1211. In this embodiment, there are eight lifting hydraulic cylinders 111. Each support gantry 121 has one lifting hydraulic cylinder 111 at both ends, and each corner of the support platform 122 has one lifting hydraulic cylinder 111. The lifting and lowering of the support frame 12 is achieved by the lifting and lowering drive of the eight lifting hydraulic cylinders 111.

[0036] Reference Figure 1 and Figure 2The support frame 12 also has a support platform 122 arranged perpendicularly to the transport path of the container 3 for operator work. The support platform 122 is located between the two sets of welding mechanisms 2, making it easy for operators to observe the welding situation on both sides. Adjusting the lifting hydraulic cylinders 111 on the two side platform frames 11 can control the raising and lowering of the support frame 12.

[0037] Reference Figure 1 and Figure 2 A pressure plate mounting bracket 112 is provided on the side of the welding mechanism 2 away from the support platform 122, in which the support frame 12 is located. The welding mechanism 2 includes a pressure plate member 24 arranged laterally on the side away from the support frame 12 and a drive assembly mounted on the support frame 12 to drive the pressure plate member 24 to rise and fall. In this embodiment, the drive assembly is a hydraulic cylinder 25. The hydraulic cylinder 25 is fixed on the pressure plate mounting bracket 112, and the piston rod 251 extends downward. The end of the piston rod 251 is connected to the end of the pressure plate member 24. The hydraulic cylinder 25 can drive the pressure plate member 24 to rise and fall on the container top plate, thereby pressing the container top plate tightly with the pressure plate member 24.

[0038] Reference Figure 1 and Figure 3 Each pressure plate component 24 has a cushioning pad structure 241 at its bottom. The cushioning pad structure 241 is an elastic cushioning material laid on the bottom of the pressure plate component 24, forming an elastic cushioning element. When the pressure plate component 24 is pressed against the container top plate, the lower side of the cushioning pad structure 241 abuts against the upper surface of the container top plate, cushioning the downward pressure of the pressure plate component 24 and reducing damage to the surface of the container top plate.

[0039] Reference Figure 1 and Figure 3 The mounting frame 1 is also equipped with a limiting assembly to prevent the pressure plate 24 from falling. The limiting assembly includes limiting cylinders 113 respectively arranged corresponding to the ends of the pressure plate 24. Each limiting cylinder 113 has a retractable limiting piston rod 1131 and a limiting support plate 1132 installed at the end of the limiting piston rod 1131. The protruding end of the limiting piston rod 1131 of the limiting cylinder 113 faces the pressure plate 24, and the limiting support plates 1132 at the ends are located on both sides of the pressure plate 24 after it is raised. When the pressure plate 24 is raised, the limiting piston rod 1131 of the limiting cylinder 113 extends, and the limiting support plates 1132 abut against the bottom surfaces of both ends of the pressure plate 24, providing support for the pressure plate 24 and reducing the probability of it falling.

[0040] Reference Figure 1 The welding mechanism 2 also includes a welding head 21, a lifting assembly 22 for driving the welding head 21 to rise and fall, and a translation assembly 23 for driving the lifting assembly 22 to move laterally and installed on the mounting frame 1.

[0041] Reference Figure 4 and Figure 5 The translation assembly 23 is installed along the length of the welding crossbeam 1211 and includes a drive rack 231 mounted laterally on the welding crossbeam 1211, three transverse slides 232 slidably mounted laterally on the welding crossbeam 1211, a drive gear 233 rotatably mounted on each transverse slide 232 and meshing with the drive rack 231, and a second drive motor 234 mounted on each transverse slide 232 and drivingly connected to the drive gear 233. A drive groove 12111 for mounting the drive rack 231 is provided on one side of the welding crossbeam 1211, and a drive rail 12112 for sliding the second drive motor 234 is provided on the top side. The output shaft of the second drive motor 234 faces downwards and the drive gear 233 is coaxially fixed to its end. The second drive motor 234 rotates, driving the drive gear 233 to rotate. The teeth of the drive gear 233 can move along the drive rack 231 through meshing with the drive rack 231. The transverse slide 232, which is rotatably fixed to the drive gear 233, moves along the direction of the welded crossbeam 1211 under the drive of the drive gear 233. In this embodiment, the translation component 23 includes three transverse slides 232, and each of the three transverse slides 232 is equipped with a drive gear 233 and a second drive motor 234.

[0042] Reference Figure 4 and Figure 5 The lifting assembly 22 is installed at the bottom of the transverse slide table 232 and includes a lifting bracket 221, a lifting platform 222 vertically slidably installed on the lifting bracket 221 for mounting the welding head 21, a lifting screw 223 rotatably installed on the lifting bracket 221 and arranged vertically, a screw nut 224 installed on the lifting platform 222 and cooperating with the lifting screw 223, and a first drive motor 225 for driving the lifting screw 223 to rotate. The lifting bracket 221 is vertically fixed to the bottom of the transverse slide table 232. The side of the lifting bracket 221 near the support frame 12 is provided with a lifting slider 2211 for the lifting platform 222 to be embedded in. The side of the lifting platform 222 that abuts against the lifting bracket 221 is provided with a lifting groove 2221 that cooperates with the lifting slider 2211, so that the lifting platform 222 can slide up and down on the lifting slider 2211.

[0043] Reference Figure 1 and Figure 5A first drive motor 225 is coaxially mounted on the top of the lifting screw 223. The output shaft of the first drive motor 225 points vertically downward, enabling the first drive motor 225 to drive the lifting screw 223 to rotate. A screw nut 224, which is threadedly engaged with the lifting screw 223, is installed on the lifting platform 222. When the lifting screw 223 is rotated, the screw nut 224 can rise along the thread of the lifting screw 223, driving the lifting platform 222 to rise. A welding head 21 is also fixed at the bottom of the lifting platform 222. When the lifting platform 222 descends, the welding head 21 descends accordingly, reaching the gap in the top plate of the container, where the welding head 21 is activated to perform welding.

[0044] Reference Figure 1 and Figure 4 The lifting platform 222 is equipped with baffle assemblies on both sides of the welding head 21. Each baffle assembly includes a baffle plate 2222 made of flame-retardant material. The top of the baffle plate 2222 is fixedly connected to the lifting platform 222, and the bottom of the baffle plate 2222 is spaced apart from the welding head 21. When the welding head 21 welds the container top plate, the baffle plate 2222 can block the welding sparks generated during welding, reducing the impact on other welding areas.

[0045] Reference Figures 1 to 5 The implementation principle of a transverse welding device for container roof in this application embodiment is as follows: When the leading edge gap of the container roof plate moves to the underside of the welding head 21 in the welding mechanism 2, the piston rod 251 in the limiting assembly retracts into the limiting cylinder 113, and the drive assembly is activated to lower the pressure plate 24 to press the container roof plate; the first drive motor 225 in the lifting assembly 22 drives the lifting platform 222 with the welding head 21 to lower to the required welding height, and the second drive motor 234 in the translation assembly 23 drives the lifting platform 222 with the lifting assembly 225 to lower to the required welding height. The transverse slide 232 of the container 2 evenly distributes the three welding heads 21 in the gap of the container top plate. After the welding heads 21 are started, the translation component 23 moves along the welding beam 1211, driving the three welding heads 21 to weld the gap. After welding is completed, the first drive motor 225 in the lifting component 22 drives the lifting platform 222 with the welding heads 21 to rise. The drive component is started to lift the pressure plate 24, and the limit piston rod 1131 in the limit component extends from the limit cylinder 113 to provide support for the pressure plate 24. The container 3 is moved so that the rear edge gap of the container top plate is moved to the side directly below the welding head 21 in another welding mechanism 2. The other welding mechanism 2 repeats the above steps to complete the welding of the rear edge gap of the container top plate.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
